       This  is  the low-level driver for the Intel i82365sl PCMCIA host controller, and many de-
       rivative controllers.  It also implements the Intel  "Yenta"  register  specification  for
       CardBus	bridges.  Common clones of the i82365sl include controllers made by Cirrus Logic,
       IBM, O2Micro, Omega Micro, Ricoh, SMC, Texas Instruments, Toshiba, Vadem, and  VLSI.   The
       overwhelming majority of current PCMCIA controllers, and all CardBus bridges, are register
       compatible with the i82365sl.  This driver is used by Card Services  for  configuring  the
       host controller, and for monitoring card status change events.

       An  ISA	i82365-compatible  controller normally sits at the IO addresses 0x3e0-0x3e1.  Two
       ISA controllers can cooperate to share the same IO ports, supporting a total of four sock-
       ets.   A  second pair of controllers can be located at 0x3e2-0x3e3.  Probing at this posi-
       tion is controlled by the extra_sockets parameter.  This only affects ISA bridges: the PCI
       bridge  probe handles multiple controllers automatically.  The driver will support a maxi-
       mum of eight sockets.

CardBus interrupt delivery
       CardBus bridges generally support both PCI and ISA interrupt signals, and multiple methods
       of  deliving  interrupt	events to the host system.  The system BIOS is partly responsible
       for correctly configuring the bridge to match the implemented interrupt hardware  at  boot
       time.   This module provides several parameters for overriding this default interrupt con-
       figuration.  The pci_int and pci_csc settings can be used to control use of PCI interrupts
       for  card  interrupts or card status changes.  The irq_mode setting, for bridges that sup-
       port it, can be used to select an interrupt delivery method.

       When the i82365 module is loaded, it performs a scan of free ISA interrupts  to	determine
       which ones appear to be usable for PCMCIA events.  The interrupt scan results are reported
       in the system log.  A successful scan will report a list of interrupts as ``scanned'';  if
       no  interrupts  appear to work, then a ``default'' list is reported.  Some bridges (Cirrus
       non-CardBus bridges, some Toshiba bridges) do not support the software interrupt test  and
       will always report a ``default'' list.  In other cases, this may be a sign of an incorrect

	      Selects the PCMCIA debugging level.  This parameter is only available if the module
	      is compiled with debugging enabled.  A non-zero value enables debugging.

	      Sets  the  base  I/O  port  address  of  the  i82365sl chip.  The default is 0x3e0.
	      Applies only to ISA-to-PCMCIA bridges.

	      Causes the driver to ignore a single socket.  Sockets are numbered starting  at  0.
	      The  socket will be left in whatever state it was already in, so it can be used for
	      cards with point enablers that do not cooperate with Card Services.

	      A flag indicating if the driver should probe at IO base 0x3e2 in	addition  to  the
	      default  0x3e0  base.   The default is 0 (do not probe at 0x3e2).  Systems with two
	      independent ISA-to-PCMCIA controllers (say, one internal and one in a docking  sta-
	      tion)  may  require  this  flag to be set.  If this flag is set, then poll_interval
	      will automatically be enabled.

	      This flag specifies that all free ISA interrupts should be tested to  see  if  they
	      can be triggered by the PCMCIA controller.  The default is 1 (true).

	      Specifies  the  set of interrupts that may be allocated by this driver, if they are
	      otherwise available.  The default list is 3, 4, 5, 7, 9, 10, 11, 12, 14, and 15.

	      Sets the interrupt line to use for monitoring card status changes.  The default  is
	      0, which means pick the highest-numbered legal interrupt not already in use.  Legal
	      values are 15, 14, 12, 11, 10, 9, 7, 5, 4, and 3.

	      Sets the card status polling delay, in 1/100 second increments.  If this	parameter
	      is  set,	card  status  interrupts  will	be  disabled.  A reasonable value is 100.
	      Polling only affects detection of card insert and eject events.

	      Sets the length of a host bus cycle, in nanoseconds.  The default is 210 ns, corre-
	      sponding to a standard 4.77 MHz clock.

Options for CardBus controllers
	      This  flag  indicates if the PCI bus should be probed for PCI-to-PCMCIA and/or PCI-
	      to-CardBus bridges.  The default is 1 (true).

	      A flag indicating if write posting (a performance feature) should be enabled.   The
	      default is 1 (true), except on certain TI 1130 bridges.

	      Specifies  that  card  status change interrupts should be routed to PCI interrupts,
	      for CardBus controllers.	The default is 1 (true).

	      Specifies that functional interrupts for IO cards should be routed  to  PCI  inter-
	      rupts,  for  CardBus  controllers.  The default is 1 (true), except on systems that
	      require use of PCI interrupts.

	      The Linux kernel sometimes cannot deduce the PCI interrupt assignments for  CardBus
	      sockets.	 If  this information can be determined some other way, it can be entered
	      here.  The Nth socket will get the Nth interrupt number from the list.

Options specific for Cirrus controllers
       When the i82365 driver is loaded, it will try to determine what interrupts can  safely  be
       allocated  for  use  by PCMCIA devices.	Cirrus controllers support some optional features
       that interfere with the use of certain interrupt lines.	Cirrus chips also lack the  func-
       tionality  needed  to  detect  whether  or  not	an  interrupt  can be used.  The has_dma,
       has_ring, and has_led options are used to specify if these features are implemented.

	      A flag indicating if the controller has DMA support.

	      A flag indicating if the controller is wired for a disk status LED.  This is set by

	      A  flag indicating if the controller's "ring indicate" signal is implemented.  This
	      is set by default.

	      A flag indicating that the controller should be set up in "frequency bypass"  mode.
	      This  disables  the  normal  7/4	clock  multiplier,  and slows down all PCMCIA bus
	      access, for systems with fast system clocks.

	      Sets the bus setup time, in internal clock cycles. The default is 1.

	      Sets the bus command time, in internal clock cycles. The default is 6.

	      Sets the bus recovery time, in internal clock cycles. The default is 0.

	      A flag indicating if the probe function should attempt to wake up a suspended  con-
	      troller chip.  The default is 0.

	      A  flag for the PD6729 PCI controller, indicating that the PCI bus speed exceeds 25

	      For the PD6729 PCI controller, specifies the interrupt delivery mode.  The  default
	      is  to  use  ISA bus interrupts; a value of 1 selects PCI interrupts.  This must be
	      set for correct operation of some PCI card readers.

Options specific for Ricoh CardBus controllers
	      Selects the interrupt routing method.  A value of 0 selects only PCI interrupts;	1
	      selects  ISA interrupt routing, and 2 selects ISA interrupt routing via an external
	      serial interrupt controller.  The default is to use whatever ISA routing method  is
	      already enabled.

	      Sets the bus setup time, in internal clock cycles. The default is 3.

	      Sets the bus command time, in internal clock cycles. The default is 6.

	      Sets the bus hold time, in internal clock cycles. The default is 1.

Options specific for Vadem ISA controllers
	      This  flag  specifies  that PCMCIA bus cycles should be clocked asynchronously from
	      host bus cycles.	It effectively adds a wait state to some operations.

	      For the VG469, this flag adjusts certain socket signals for driving a  socket  con-
	      nected via a cable.

Options specific for TI CardBus controllers
       Normally, a system's BIOS will configure these options appropriately, so all these options
       default to leaving these features configured the way the driver finds them.

	      A flag indicating if the controller is wired for "ring indicate".  The  default  is
	      to read the current setting from the controller.

	      Selects  the interrupt routing method.  A value of 0 selects only PCI interrupts; 1
	      selects ISA interrupt routing; 2 selects ISA  interrupt  routing	via  an  external
	      serial  interrupt  controller;  and  3  selects serial routing for both PCI and ISA
	      interrupts.  The default is to use whatever routing  method is already  active,  or
	      ISA routing if no method is enabled.

	      A  flag,	indicating  if	the P2CCLK pin should be configured as an input (0) or an
	      output (1).  This signal is used for communicating with a socket power  controller;
	      if set incorrectly, the bridge will be unable to power up cards.	The default is to
	      use the BIOS setting.
